Gas pressure question

[IanCC]

If the cooker is really old, is there a screw headed valve on the gas inlet at the back of the cooker? Or a capped needle valve. Or a partially blocked gauze filter.

Corrosion or debris in the manifold inside the cooker?

Try the cooker connected by a short length of hose to the new regulator. If all works you have a plumbing issue.

In an open space check flow from the new regulator (Be aware some regs have a 'pipe failure' automatic shut off.)

Where would i look for gauze filter? Thanks for your time and input. Plastimo cooker.

If the inlet has a removable hose tail, in there.
There may be something that looks like a miniature version of this:

Thanks, but unfortunately not. Just a spur for pressure testing. I will get a pipe to connect direct bottle to cooker and take it from there. Thanka again, ian.
